Factors to be considered for resuming international travel
Each country should conduct a risk-benefit analysis and decide on its priorities.
WHO recommends that priority should be given to essential travel for emergencies, humanitarian actions (including emergency medical flights and medical evacuation), travel of essential personnel (including emergency responders and providers of public health technical support, critical personnel in transport sector such as seafarers and diplomatic officers), and repatriation. Cargo transport should also be prioritized for essential medical, food and energy supplies. Sick travellers and persons at risk including elderly travellers and people with chronic diseases or underlying health conditions, should delay or avoid travelling internationally to and from areas with community transmission.
There is no “zero risk” when considering the potential importation or exportation of cases in the context of international travel. Therefore, thorough and continuous risk assessment and management will help identify, reduce and mitigate those risks, while balancing the socio-economic consequences of travel measures (or temporary restrictions) against potential adverse public health consequences.
The decision process should include an analysis of the situation, taking into account the local context in countries of departure and destination. The following factors should be considered: local epidemiology and transmission patterns, the national public health and social measures for controlling the outbreaks in both departure and in destination countries; public health and health service capacity at national and subnational levels to manage suspect and confirmed cases among travellers, including at points of entry (ports, airports, ground crossings) to mitigate and manage the risk of importation or exportation of the disease; and the evolving knowledge about COVID-19 transmission and its clinical features.
